Chapter 6: Using the Software

Browser choice

When installation is complete, the Java program runs automatically in the background as a plug-in supporting the MultiVOIP GSM web interface. No user actions are required.

After the Java program has been installed, you can access the MultiVOIP GSM using the web browser interface. Close the MultiVOIP GSM Windows interface. Start the web browser. Enter the IP address of the MultiVOIP GSM unit. Enter a password when prompted. (A password is needed here only if password has been set for the local Windows interface or for the MultiVOIP GSM’s FTP Server function. See “Setting a Password -- Web Browser interface” earlier in this chapter.) The web browser interface offers essentially the same control over the VOIP as can be achieved using the Windows interface. As noted earlier, logging functions cannot be handled via the web interface. And, because network communications will be slower than direct communications over a serial PC cable, command execution will be somewhat slower over the web browser interface than with the Windows interface.
